I404 - 4 Channel Charge Integrating Digital Electrometer
The I404 is intended for the measurement of small charges or corresponding currents (from pA to µA) generated by devices such as ionization chambers, in-vacuum beam position monitors, proportional chambers, and photodiodes. Four input channels make the I404 particularly well-suited to four-quadrant electrode systems used for beam centering. The I404 includes an integrated high-voltage supply, suitable for biassing detectors.
See the I400 for an electrometer offering high voltage biased inputs, suitable for thimble ionization chambers.
See the IC101 for an electrometer with a single channel.
